commit aa687ac341408229e0a27f19f8266b28a291fdb1 Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Sun Mar 9 17:46:39 2014 +1100
mainboard/jetway/nf81-t56n-lf: Fix GPP missing CLK on PCI bridge.
The platform dependent mainboard.c was incorrectly disabling the second clock signal feeding the GPP ports. This results in spurious hangs by calling the set_pcie_dereset() SB CIMx callback many times. This also stops coreboot from finding the second NIC behind the pci 15.0 bridge.
